Hey thanks for your help... Below is the O/P

@juredd1
I removed all the entries from .rhosts file and just put [+] sign.

Code:
serverA>host serverB
serverB.t.com is 10.116.169.52

ServerC>host serverB
serverB.t.com is 10.116.169.52

ServerB>host serverA
serverA.t.com is 10.116.214.81
ServerB>host serverC
serverc.t.com is 10.116.214.83

@zaxxon

there was no O/p of below commands

Code:
grep -vE "^#|^$" /etc/netsvc.conf
grep serverA /etc/hosts
grep serverC /etc/hosts


Code:
$ time nslookup dseax202
Server:  tedns01v.t.com

It doesn't look like zaxxon is currently online so I through this out there. Looks like the nslookup response times are good but the answering DNS server is the second one in your resolv.conf list for some reason. No DNS expert here but you might try swapping the nameserver entries around so the 10.64.40.215 is the top one.

I don't recall what the default ordering of name resolution is if the netsvc.conf file does not have an entry but you could try putting the host names in the /etc/hosts file. If I read your code correctly those are not currently there. Will look something like below:
Code:
10.1.1.1 serverA.t.com serverA

Then vi your /etc/netsvc.conf file and enter
Code:
hosts=local,bind4

at the bottom of your netsvc.conf file. This would tell the system to look in the /etc/hosts file before searching the dns records.

If it doesn't help you can remove the changes I suggested.

To everyone reading if I have this wrong please correct me.

My answer would have been very similar Smilie
With vmstat I wanted to make sure your box is not having performance issues. The vmstat is something you could check on the servers you are trying to connect to, just to make sure, they are not too busy to bring up the login in an acceptable amount of time.

Hi,

regarding your /etc/resolv.conf:
you have both - a domain entry and a search entry - what is wrong on AIX. The domain entry and search entry are mutually exclusive, so if both entries are used, the one that appears last will override the other. Please have a look here.
Kind regards

Absoluteley right what zxmaus says and the docu also states

Quote:
The search entry can have from one to six DomainName variables.
You have 7 entries.

Not sure if this is the reason for the problem but this makes it more conform to the config rules.
